This paper presents a novel method to detect the harmonic and reactive current of nonlinear load under the non-ideal supply voltages, i.e. unsymmertical and distorted voltage conditions. The proposed method is based on the rotating coordinate transformation and projection of three-phase currents and voltages simultaneously. It can extract positive-sequence fundamental active component of load current, andthereby determine the harmonic and reactive current of the loads.
